atomic coin scam our coins 
No, it's not atomic coin, it's just one scammer.
Very good documentation! There should be more about the history of Atomic Coin: How did the team disappear, who is Putincoin and why do Bitcointalk let him scam so hard?
I don't know much about history of team. User AtomicProject (I believe you mean him when say "who is Putincoin") started new thread in [ANN] and kept it live for some time, and then Dec2017 happened.
I asked moderator (mprep) why can't he punish scammer, but he refers to https://bitcointalk.org/index.php?topic=703657.0:

Q: Why haven't you banned who is an obvious scammer?
A: Possible (or real, not for me to decide) scams are not moderated to prevent moderator abuse. If we start picking out which ones we call "scammers" and ban, we would make a lot of decisions based on biased opinions.

Seems legit, but it means we as community should report about scam actions ourselves. There is a "trust" tool for this, and I wonder, why no one use it for reporting AtomicProject's scam before.
